Check Digit Verification of cas no
The CAS Registry Mumber 121732-07-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,3 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121732-07:
(8*1)+(7*2)+(6*1)+(5*7)+(4*3)+(3*2)+(2*0)+(1*7)=88
88 % 10 = 8
So 121732-07-8 is a valid CAS Registry Number.

Functionalization of Phenyl Rings by Imidoylnitrenes
Dabbagh, Hossein A.,Lwowski, Walter
, p. 3952 - 3957 (2007/10/02)
The electrophilic reactivity of imidoylnitrenes ROC(=NZ)N can be controlled by the choice of Z.With Z = SO2CH3, benzenes react only if they bear electron-donating substituents.The resulting N-arylisoureas, ROC(=NZ)NHAr, can be obtained conveniently and in
